Biomedical robots of all shapes and sizes fascinated attendees at IEEE’s ICRA 2017 robotics conference in Singapore. A robot the size of a capsule is designed to be swallowed so it can look around your stomach for anything that looks suspicious. The robot wields a needle to draw in biopsy samples of tissue that physicians can then analyze for signs of cancer or disease. The biggest challenge with this brilliant idea is getting the robot out of the patient’s stomach once it is in there. The designing scientists at Max Planck Institute for Intelligent Systems in Stuttgart, Germany, are still working on that. Another group of scientists from the University of Illinois at Urbana-Champaign presented a remarkably flexible electronic prosthetic hand that they then demonstrated using various finger torture devices that smashed, twisted, and bent the fingers in every direction. The key to the advance was replacing breakable parts with flexible parts. Even after being smashed with a hammer, the hand could pick up the hammer, or other more delicate items, as if nothing had happened. Researchers like to play, and it was only a matter of time until they made robot worms. One worm designed by a research group from the University of Colorado, Boulder, sported a three-section body that wrinkled up and expanded to propel itself along inside a person’s intenstine using three shape-memory alloy springs that compress and expand. The worm robot can move 15 centimeters in 6 minutes and is expected to be less painful than a colonoscopy.
